新下载的cocos2d-x 3.8，新建项目，用xcode 7 打开之后，直接编译 ios 版本，报错如下
ld: in /Users/xxx/Library/Developer/Xcode/DerivedData/xxx-fyfxmjfdrhfqhqfplqsmqezxqnwr/Build/Products/Debug-iphonesimulator/libcocos2d iOS.a(ftbase.ios8_x86_64.o), building for iOS simulator, but linking in object file built for OSX, for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
请教各位大神如何破解
